Question

a piece of wire is 190cm long.it is bent to from an isoceles triangle.with tha base measuring 75cm. what is the length of the other two equal sides​

Answer 1

Step-by-step explanation:

Sum of three sides of triangle =190 cm

Perimeter of isosceles triangle =base +2side

190 =base +(2*side)

190 =75+(2side)

190-75=2side

115 = 2 side

$115 \div 2 cm= 57cm \: 5mm$

Each side is 57.5 cm or 57 cm 5mm

Answer 2

Answer:

let the 2 equal sides be x and x

so 75+x+x=190

=>75+2x=190

=>2x=190-75=115

then, x=115/2= 57.5cm

The length of 2 equal sides are 57.5cm
